# Logic is as follows:

#   2. Check if current word is a global option; if so, propose completion.
#   3. Check for the presence of a main command (qdisc|class|filter|...). If
#      there is one, first call _tc_direct_complete to see if previous word is
#      waiting for a particular completion. If so, propose completion and exit.
#   4. Extract main command and -- if available -- its subcommand
#      (add|delete|show|...).
#   5. Propose completion based on main and sub- command in use. Additional
#      functions may be called for qdiscs, classes or filter options.
